IPC: G10K9/13
Filed: 2020-05-27
Abstract: A peak current buzzer driving circuit, comprising a switching tube (106) and a control unit (300). The switching tube (106) connects an electromagnetic buzzer (109) to a system input voltage (VIN) when turned on, and disconnects the electromagnetic buzzer (109) from the system input voltage (VIN) when turned off. The control unit (300) is used for outputting a PWM signal, so that the switching tube (106) is turned on when the PWM signal is at high level and is turned off when the PWM signal is at low level. The control unit (300) is provided with a sampling circuit (107). The sampling circuit (107) comprises a sampling resistor connected to the switching tube (106) in series. The control unit (300) dynamically outputs, according to the system input voltage (VIN) and an electrical signal on the sampling resistor, a PWM signal meeting a condition II, sets a period T of the PWM signal as a fixed value according to a condition I, and controls the real-time duty ratio D(t) of the PWM signal by means of a formula I set according to the condition II. Under a high system input voltage, the real-time duty ratio D(t) can be decreased to ensure the normal operation of the electromagnetic buzzer, and the problem of excessively low sound pressure of the electromagnetic buzzer under the high system input voltage due to the excessive decrease of the real-time duty ratio D(t) can also be solved, so that the sound pressure of the electromagnetic buzzer has a small change in a wide system input voltage range. It has been verified that the provided driving circuit can control the sound pressure deviation of the electromagnetic buzzer within +/-3db in a wide input range of 3-24 VDC. Therefore, the peak current buzzer driving circuit can be compatible with a relatively wide system input voltage range, and can ensure low power consumption and high sound pressure consistence in a wide system input voltage range.
